What is the best movie player of iOS - OPlayer vs AVPlayer vs GoodPlayer

I have tested pretty much on any sample video vile I could find on internet including various extensions, containers, codecs, including files with issues, from very old video files (10y+) to 1080p

Here is my list top-to-down.

1, OPlayer (my favorite)

- plays almost all movie formats I was able to find on internet with exception of: WRF and some old AVI and MOV files

- good performance

- not much configuration options

- background playback

- Dropbox integration (pro version)

- easy controls

- they removed AC3 because of patent issues (some vids may play not sound)

2.AVPlayer (backup if I need to adjust colors or need use gestures to go back and forth..)

- plays most formats but there were several files it didn't play: VOB, some MOV, AVI, MP4, SFW and WRF

- very good configuration options

- can adjust color/saturation/brightness during playback

- gestures

- good performance

3. GoodPlayer (no real reason to keep this one; I keep it just in case because it can do Audio Volume Boost and a few other tweaks)

- interface is so-so, not the best but OK

- very choppy performance on 1080p

- doesn't play some MOV, AVI

- didn't play any SWF (Flash files) I tried (disappointing)

- amazing array of configuration options

- gestures
